Ehrenburg Castle was built on a promontory in the Ehrbach valley (Ehrbachtal), a tributary valley of the Mosel. It was once used as the fortified centre of a small reign between Mosel and Rhine. Today it is a cultural monument (Kulturdenkmal) with a variety of events. The oldest, still preserved part of this castle is the remains of a steady house, a rectangular residential tower. It is assumed that the construction work, for this at first small castle of the Staufer, started in the first half of the 12th century.
